small western mirror with mercury added to the glass (Edo period)
Historical term for a type of mirror produced during the Edo period. The name literally means 'conceited mirror' or 'self-admiring mirror', possibly because the mercury backing gave a clearer reflection, encouraging vanity.

I saw a rare self-admiring mirror at the museum.
和鏡 refers to traditional Japanese mirrors (usually bronze), while 自惚れ鏡 is a specific type of western-style mirror from the Edo period.
Standard kanji spelling with regular okurigana.
Variant using 己 instead of 自; less common but still encountered.
Irregular okurigana usage; 惚れ is shortened to 惚.
Irregular okurigana usage with 己 variant.
Compound of 自惚れ (うぬぼれ, 'conceit, self-admiration') and 鏡 (かがみ, 'mirror'). The name likely arose from the improved clarity of the mercury-backed glass, which made one's reflection more flattering.
